T @ZZ whom, it may concern:

Be it known that l, EPHRAIM W. Livna MORE, a citizen of the United States, and a resident of Bellingham, in the county of vWhatcom and State of Washington, have invented a new and Improved Exhibiting-Reel for Mutoscopes, of which the following is a full, clear, and exact description.

This invention relates to exhibiting apparatus, and. the object of the invention is to present to the view of an observer a number of specimens of the eggs of fishes or animals of the lower order, and representing the same in successive stages of development, from the egg to the fully developed young creature.

More specifically, the object of the invention is to provide a reel, together with its accessories, which may be readily set up in a mutoscope of ordinary construction and such as are now used for exhibiting a succession of pictures.

The invention consists in the construction and combination of parts to be more full Y described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a mutoscope, the wall of which is represented as broken away so as to illustrate my exhibiting reel mountedin the interior of the device; Fig. 2 is a cross section through the exhibiting reel taken upon an enlarged scale Fig. 3 is a section on the line 3`3 of Fig. 2 and passing through one of the vials in which the specimens are held and Fig. 4 is a perspective representing a shoe whichis adapted to be slid over the pawl usually found in such machines, for the purpose of attaching the pawl to the particular construction of reel which is used.

Referring more particularly to the parts, 1 represents the case of the mutoscope, which case is provided at a suitable point with an opening covered by an eye-shield 2 through which the observer may look in order to see the specimens which are p resented to view.

i As shown, the machine case is of substantially circular form, and is provided witha fixed horizontal stud 3 upon which there is mounted my reel 4. The construction of this reel is very clearly shown in Figs. 2 and 3 it presents two heads 5 and 6, which are r l l attached to the end faces of'a drum 7 of circular form. ln the face of this drum 7 there is formed a longitudinally disposed gutter or channel 8, and this channel affords means for attaching the ends of a band or strip 9, of paper or similar material, which extends continuously around the drum. The ends of this strip are secured .in the channel 8 by means of a bar 10 which lies in the bottom of the channel and which is held in position by a suitable fastening device such as the screw 11, as illustrated. As shown most clearly in Figs. 2 and 3, each of the heads 6 projects beyond the lateral surface of the drum, and on its inner side is provided with a plurality of circular pockets 12, and in the bottom of these pockets l provide cushions 13, of depressible material, such as rubber. The edge of the head 5 projects beyond the edge of the drum 7 in a similar manner, and at points opposite to the pockets 12, the inner side of this head is provided with notches or recesses 14 which extend in from the edge of the head as indicated..

The specimens are held in a plurality of vials 15 which are mounted in the notches and the pockets 12. ln order to facilitate the mounting of the same, these vials are preferably formed each with a projecting boss 16 in its bottom, which is received in one of the pockets l2. Each vial is suitably closed by a suitable stopper 17, and over this stopper there is received a cap 18 having a cushion 19 which seats against the end of the vial, and this cap is held in position by a suitable set screw 20 which passes through the head 5 from the outer side thereof. It should he understood th at these vials contain the eggs of fishes, toads or similar creatures, arranged in a series or stages which represent the eggs as they progress through their period of incubation until the perfect creature is formed. ln order to preserve the eggs and the creatures, the vials should contain a mixture of formaldehyde and water, in the proportion of about one part of formaldehyde to eighteen parts of water. This mixture will preserve the specimens, but will not change their color or in any way al'lect their natural appearance.

The reel 4 is rotated in the usual manner by a sha'i't 21 operated by a crank 22, the said shaf t carrying a worm 23 which drives the reel through the medium of a worm wheel 24, in the usual manner. By means of the crank 22, the operation of which is possible after the insertion oi a coin at a suitable point indicated at 25,the specimens maybe brought in succession below the ohservers eye. Sutiicient illumination is produced by an incandescent lamp 26 mounted within the case, and. which, in practice, is operated automatically in the usual manner.

The case l is 'provided with a cover 27 having a hinge connection 2S which enables the same to be opened at will for the purpose ot replacing or removing the reel or attending` to the interior oi the device. On the opposite wall 28L oi the ease, an outwardly projecting stud 2f) is provided, upon which there is rotatably mounted a pawl 3i), which has substantially the iorm shown in Fig. 4. This pawl is usually Yliound in macliines oi this class, and it consists simply oi' a wooden block, presenting a l'lat iace 3l disposed toward the reel and a curved rear vtace, so that an edge .is presented whichv is held against the 'tace ot the reel by means of a coiled spring 33, the said spring being attached to an ear S4 which projects up Vfrom the upper side .oi the pawl, as indicated. llt should be understood th at this pawl 30 is such as is usually found in machines oi this class and ot a certain type. The general purpose et this pawl is to prevent a backward movement oi the reel. It is, however, unsuited to the construction of reel which is necessary in connection with my invention. In order to adapt it ier co-operation with the reel 4, l provide a shoe 35, the construction oil which is very clearly shown in Fig. 4. T his shoe is formed with a body 36, which conforms partly in outline to the pawl 3() and which is adapted to be slid longitudinally over the same, as will be readily understood, the said shoe seing retained. in position by means oi. a projectingl lip 37 which overhangs the upper extremity ol the pawl, and by an inwardly p rejecting Vlinger 3S which is more or less resilient, and which is adapted to project down over the inner edge 39 ot the pawl. rllhe shoe 3.6 presents a l'lat side vace 40 which is ad apted to come against the outer side Vlace ol the pawl, and the lower portion of the shoe is formed into a rudimentary shell 4l which incases the inner end of the pawl. To the lower portieri of the shoe there is attached a transverse bar 42, the extremities whereof rest against the edges ot the heads 5 and 6. From an inspection oi Fig. 3, it will he observed that the edges ot these heads are in alinement, that is, the heads are of the same diameter.

By means of the cra-nk 22 the reel will be rotated so as to bring the specimens successively into View, and the portion et the band 9 which lies adjacent to the successive specimens will describe the stage oi' development which they represent. YWhen the reel has made a complete revolution, the notch or channel S will come under the pawl and shoe 36; whereupon, the spring 33 operates to throw the bar 42 into the notch. ln this way a further rotation ol" the reel is prevented. In Fig. l., the channel S is represented in dotted outline, in the position which it assumes when the further movement oi the mechanism is about to be arrested. At this time, the upper end or tail oi the pawl 30 comes against a stop-pin 42% which is attached. to the side wall 2S ol' the fase. .ln order to enable the reel 4 to he readily mounted within the case, its drum 7 is provided. with a central bore 44 which receives a bushing 45 as illustrated in F ig. l, and the reel is held in position by means of a split pin 46, which is also illustrated in. Fig. l..

The reel constructed as described, together with the shoe, may be quickly applied to the, mechanism of a mutoscope of the type dcscribed, the picture reel thereol" being `irst removed., as will be readily understoml.. In this way, a very interesting and instructive exhibit may be made. The specimens carried in the reel may be readily changed when desired. In this connection, special attention is called to the iiorm of the vials, which -facilitates their easy removal lrom the posi.- ti on in which they are held..

Having thus described my invention, l claim as new and desire to secure by Letters Patent:
